I'm in Naruto, but the system says I'm in One Piece.

"What?!"

Kakuzu stared intently at Hoshino Yu, who had transformed into a ball of lightning in the distance, his heart pounding with fear, his vigilance at its peak.

At such close range, he could not sense the massive chakra fluctuations, but even from a distance of hundreds of meters, he could still feel the dazzling and scorching lightning.

Most importantly, he now considers the other party to be a ninja from Kumogakure (Hidden Cloud Village), otherwise there's no way to explain where the other party came from.

But no matter what, he wouldn't just stand there quietly and wait for the other party to finish loading the skill bar.

Kakuzu's entire body tensed up, and the tentacles behind him, adorned with a wind-style mask, began to writhe.

Just as he was rapidly forming hand seals, preparing to unleash "Wind Release: Pressure" once more, Hoshino Yu moved.

At this moment, Hoshino Yu felt that everything had become extremely slow, and he had the feeling that he could instantly reach a designated location if he wanted to.

He certainly doesn't have any lightning flash or thunder breathing techniques.

But the principle is the same.

Once the Rumble-Rumble Fruit's elemental transformation is activated, his entire body is electrified, followed by a quick draw slash—can you say it's not Issen?

The result was exactly the same: if the opponent didn't dodge, they would be cut in half.

Even Sasuke's Mangekyou Sharingan couldn't detect the Raikage's so-called "Lightning Release Armor" in the original work, let alone Hoshino Yu's true lightning elemental form.

For Kakuzu, there might be a chance to react in that extremely short time, but he certainly wouldn't be able to see it, and even if he could react, he might not be able to dodge it.

Hoshino Yu's gaze was fixed on Kakuzu, who was forming hand seals a hundred meters away. Suddenly, he slightly increased the force in his right hand, and the Kusanagi sword in its sheath slowly revealed an inch of its blade.

Immediately from his perspective, the entire world seemed to be twisted and stretched by brute force, going from stillness to lightning speed and sword-wielding in the blink of an eye.

Swah——

With a muffled thud as his body was instantly cleaved in two, Kakuzu, who was originally a hundred meters away, appeared in front of him.

Unlike his previous complete form, Kakuzu now only has his tall body remaining, his hands still in the hand seal position, while his head, along with the tentacle mask behind him, has already flown high into the air.

Clean and efficient, without the slightest unnecessary movement.

"Wow...so fast!"

Kakuzu's pupils shrank sharply as he was still shocked by the opponent's speed, which was completely beyond his ability to react.

The moment Hoshino Yu took off, he didn't react in time, but decades of experience told him he had to dodge.

However, the opponent was too fast, and there was no way to dodge, so he was beheaded with a single sword strike.

However, Kakuzu remained calm. Looking at the severed body below, where countless tentacles were wriggling, he then turned his gaze to Hoshino Yu, who was watching him from a distance.

"That troublesome brat..."

"But it seems the other side doesn't know my information," Kakuzu thought to himself, while quickly manipulating his tentacles to reconnect himself.

As he watched Kakuzu's head and body reassemble themselves, a glint of intriguing light appeared in Hoshino Yu's eyes.

"It seems okay when you read it in the comics, but it's really weird to see it in person."

"If I didn't know it was a person, I would have thought I saw a ghost."

He did not launch an attack while the other party was assembling the pieces.

The opponent's five masks are all located on their backs, and only one Wind Release mask is currently visible, clearly indicating that they are planning to ambush me.

If he really wanted to take action, with the intelligence advantage, he could instantly destroy the opponent's five masks of different chakra natures, but he already had other ideas.

If we could acquire a top-notch enforcer, wouldn't everything we do in the future be much easier?

You should know that the 600 billion explosive tags that Kuonan had were bought for her by Kakuzu.

Given that a single explosive tag is worth a thousand taels of silver, this ability to rake in money is truly admirable.

Once the angles returned to their original state, Hoshino Yu's lips curled into a slight smile as he slowly raised the Kusanagi sword in his right hand, pointing it at his opponent:

"I've long heard that the rogue ninja Kakuzu of Takigakure is immortal, and seeing it today, I can confirm it's true. It's just a pity that you're about to die here."

"Heh heh heh, ha ha ha! You think you're stronger than him?!" Kakuzu laughed, his anger barely contained. "Even the First Hokage, Hashirama Senju, couldn't kill me. You think you're stronger than him?!"

As soon as he finished speaking, another mask appeared behind him, and his hands quickly formed hand seals.

"Fire Release: Head Carving!"

"Wind Release: Pressure Damage!"

In an instant, two different types of chakra fluctuations surged on the two masks, followed by the powerful fire and wind ninjutsu bursting forth from them!

This is Kakuzu's strongest combination technique: a complex ninjutsu that uses wind to fuel the fire, creating an explosive burning propulsion and generating massive area-of-effect damage.

The desert within a radius of several hundred meters instantly turned into a sea of ​​fire, which would have been difficult to extinguish without a powerful water escape technique.

But Hoshino Yu wasn't flustered.

Seeing the massive, complex ninjutsu hurtling towards him, he flicked his left hand with lightning, slicing across the sword's blade, then coldly looked at Kakuzu and said:

"I'll kill you in one second."

In an instant, just like before, Hoshino Yu, wielding the Kusanagi Sword, transformed into blue lightning and appeared behind Kakuzu in a flash.

Before the other party could react, he swung his longsword rapidly, and in an instant, the four heart masks on Kakuzu's body, along with the two masks that were releasing ninjutsu, were destroyed by him!

By the time Kakuzu realized what was happening, he only had one life left out of his original four.

Moreover, his only remaining heart was being held against the hand of Hoshino Yu by the Kusanagi sword behind him.

With the mask destroyed, the ninjutsu naturally dissipated as well.

Looking at the scorched sand ahead billowing thick smoke, and hearing the crackling of electricity and the scorching heat behind him, Kakuzu broke out in a cold sweat, his Adam's apple bobbing.

For the second time, he felt that he was so close to death.

As for when the first time was, it was naturally the time when he went to assassinate the First Hokage.

Kakuzu was filled with doubt as to why Hoshino Yu knew his secret.

After all, most of the people who have seen his true colors are dead, so there shouldn't be someone like him.

"How was it, Kakuzu-sama?" Hoshino Yu asked teasingly, watching Kakuzu's retreating figure. "What you said is a second, it won't take longer than that."

After a moment of silence, Kakuzu's deep and hoarse voice slowly rang out:

"Who exactly are you?"

"Just a ninja who came to the Land of Wind to gather intelligence."

As he spoke, Hoshino Yu sheathed the Kusanagi sword, but the lightning around him did not dissipate.

Just kidding, what if Kakuzu tricks you while you're standing next to him?

Now that you have lightning protecting you, the high temperature should at least protect your body from the attacks of those strange tentacles. Do you really think the other party is easy to handle?

If we hadn't had prior intelligence and caught the enemy off guard with near-lightning speed, this battle probably wouldn't have ended so quickly.

Kakuzu was puzzled when he realized that the sensation of the sword pressed against his heart had suddenly disappeared.

"Hmm? Could it be that this brat really isn't intentionally trying to be my enemy?"
